The Mechanism of Life It is a self-recording instrument, composed of two distinct portions—one for record of horizontal, or rather of what are called undulatory shocks; the other for vertical shocks. The Eruption of Vesuvius in 1872 But some of these, as for example during the Lisbon earthquake in 1755, may have been mere vibrations or undulatory movements of the earth's crust prolonged from a great distance.

Adventures of a Young Naturalist While his flight is undulatory, the waviness is not so deeply and distinctly marked; nor does he sing a cheery cradle-song while swinging through the ether, although he often utters a series of unmusical chirps. Birds of the Rockies Hence the undulatory theory of light has met with much opposition, directed not against its failure to explain the phenomena, but against its assumption of the existence of a medium in which light is propagated. The World's Greatest Books — Volume 15 — Science At Cacin, three phases were distinguished, the first a slight undulatory movement coincident with the sound, followed immediately by the subsultory motion, a pause, and stronger undulations, the total duration being 15 seconds. A Study of Recent Earthquakes If these theories be true, we may hereafter ignore all undulatory processes. New and Original Theories of the Great Physical Forces Now the question suggests itself to our mind, as to what effect the atomicity of the Aether has upon the undulatory theory of light. Aether and Gravitation Indeed, a number of their notes suggested that bird, as did also their manner of flight, which was quite undulatory. Birds of the Rockies When, for example, the undulatory theory was started, it was not imagined that the vibrations of light could be transverse to the direction of propagation.

Evolution, Old & New Or, the Theories of Buffon, Dr. Erasmus Darwin and Lamarck, as compared with that of Charles Darwin But in modern investigation this is distinctly not the case; Darwin's theory, for example, like the undulatory theory, has been a motive power and not an anodyne. Fragments of science, V. 1-2 At Fontana, however, the undulatory shock was replaced by a vertical one. A Study of Recent Earthquakes Now, it seems to us that there is quite as much of hypothesis in this speculation of Laplace as in the undulatory theory of light. Blackwood's Edinburgh Magazine, No. CCCXXXVI. October, 1843. Vol. LIV. Hence our theory agrees with the undulatory theory in assuming the existence of a medium which is capable of becoming a receptacle of two forms of energy.” Aether and Gravitation This excellent volume contains James Gregory, Des Cartes, Halley, Barrow, and the optical writings of Huyghens, the Principia of the undulatory theory. A Budget of Paradoxes, Volume I When a hammer strikes a bell, the latter vibrates; and sound, which is nothing more than an undulatory motion of the air, is radiated in all directions.

Practical Mechanics for Boys Although it caused no damage, its undulatory motion was sufficiently strong to affect certain persons with a sensation akin to sea-sickness. The Ocean and its Wonders Thus it can be seen that the elasticity of the Aether, so essential to the undulatory theory, is a problem that cannot be solved apart from recognizing the hypothesis of an atomic Aether. Aether and Gravitation Young, who discovered the undulatory theory of light, could read with wonderful rapidity at the age of two, whilst at eight he had a thorough knowledge of six languages. Reincarnation A Study in Human Evolution The law of Brewster does not apply to matter in this condition, and it rests with the undulatory theory to explain why. Fragments of science, V. 1-2 The undulatory theory, now generally accepted, maintains that light is carried by vibrations in ether.

Aether and Gravitation Darwin's theory was an explanation of phenomena in Natural History, as the undulatory theory was of the phenomena of light. Thomas Henry Huxley A Character Sketch In the meanwhile, the gradual reception of the undulatory theory of light necessitated the assumption of the existence of an 'ether' filling all space. The Advance of Science in the Last Half-Century Verdet could say, in all truth, "It is not possible to deny the transverse direction of luminous vibrations, without at the same time denying that light consists of an undulatory movement."
